Abstract
In this research, the focus was on finding methods to eliminate dangerous fungi that pose a threat to human health and the environment. The study utilized the fungus Penicillium notatum to biosynthesize silver nanoparticles. The silver nanoparticles were characterized using a variety of methods, including scanning electron microscopy and ultraviolet-visible spectroscopy, which shed light on their optical and morphological properties as well as their crystallinity, to assess the effectiveness of the biosynthesis process. Researchers used nanomaterials added to SDA media to evaluate the bioactivity of the generated nanoparticles against two environmentally hazardous fungi, Aspergillus ochraceus and Cladosporium cladosporioides. The biogenic silver nanoparticles, which ranged in size from 20 to 22 nanometers, exhibited polydispersity. Especially, nanoparticles exhibited significant antifungal action, effectively inhibiting the growth of Aspergillus ochraceus and Cladosporium cladosporioides.The research presents an innovative, straightforward, and environmentally friendly approach to producing biofunctionally valuable biogenic nanoparticles. Using Penicillium notatum to synthesize silver nanoparticles allows for a natural way to produce these particles, which can be used in many ways to fight harmful fungi and other related issues. This eco-friendly method holds promise for addressing health concerns associated with dangerous fungi, contributing to the development of sustainable and effective antifungal strategies. By harnessing the natural processes of fungi, this study offers a practical means of producing biogenic nanoparticles, paving the way for more developments in the area of nanotechnology and its uses in environmental remediation, agriculture, and healthcare.
